Which Determines Acceleration, Torque or Power?

[SanEliana]

Torque determines a car's acceleration performance, but this refers to the torque at the wheels, not the engine torque. The car has a transmission system where the engine's output power passes through the gearbox and final drive before reaching the wheels, so the engine torque is not equal to the wheel torque. Additional information: Power and torque are two important performance parameters of an engine. More details are as follows: 1. Power measures the amount of work done: Power is used to measure how much work an engine can perform per unit of time. An engine with higher power can do more work in the same amount of time. 2. The relationship between power, torque, and RPM: (1) An engine with greater torque generally has higher power, as a high-torque engine can output more force with each power stroke. (2) An engine with higher RPM typically has greater power, as a high-RPM engine performs more power strokes per unit of time.
